The XBox 360 version is still cheapest at Zavvi but if you're looking for the collector's version of Dog Days then you'd best trot over to Play now. The special features are not hugely impressive, consisting of 7 exclusive weapons, 8 in-game masks and an exclusive multiplayer map. The game itself, much like the original, is similarly lacklustre. The main campaign is way too short and lacking in any kind of emotional pull or mental challenge. It all works fine but it's uninspiring and never builds any real excitement. Thankfully the co-op and versus multiplayer modes fare far better but it's questionable whether this is enough to justify the purchase. Thanks to fawcett at Hotukdeals!
